WATER-HEATER FOR GAS OR OTHER RANGES.

SPECIFICATION forming part of Letters Patent No. 640,924, dated January 9, 1900.

Application filed June 30, 1899.

To all whom it may concern.-

My invention relates to an improvement in a gas or other range; and it consists in providing such range with a water-chamber at top, an additional heating-chamber beneath the same having a floor formed hollow as a water-chamber, pipes for connecting said chambers providing for the circulation of water therebetween, a burner beneath said floor, and a spaced rim around said floor for directing the products of combustion from said burner to the upper water-chamber, they then escaping through the opening in the top plate of the range, said upper water-chamber being also adapted to be heated by a burner independent of the burner for the water-chamber beneath it.

Figure 1 represents a perspective view of a water-heater for a gas or other range embodying my invention, showing also a boiler to which the same is applicable and pipes and connections common thereto and to said heater. Fig. 2 represents a perspective view of arange detached from the boiler and pipes seen in Fig. 1, the same being broken away to show the relative position of the heatercontained in its interior, an upper waterheater employed being omitted for the sake of clearness of illustration. Fig. 3 represents a plan view of the floor of the additional heater, on an enlarged scale, removed from the body of the range. Fig. 4. represents a partial plan view and partial horizontal section of a portion of the top of the range. Fig. 5 represents a vertical section'of a portion on line a: 56, Fig. 4..

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a gas or other range which is provided with the gas-pipe B, which is omitted from Fig. 1 for clearness of illustration, said pipe being provided with the apertured branches 0, the

general contour of which can be best under stood from Fig. 3.

D designates a water-holding chamber which has secured to its outer portion the open rim E, whereby it may be supported upon the lugs F on the frame above the heater pipes C and heat may pass through the spaces of said rim as flues and over said chamber and so reach the upper water-chamber, through the opening of which and the top plate the products of combustionescape, it being noticed that the sides of the range and the chamber D form a heating chamber.

G designates a partition located in the water-chamber D and terminating near an end thereof, whereby the passage H is provided for the Water to flow from the inlet-pipe J around to the outlet-pipe K, the water flowing from the latter to the boiler L, which is utilized as a reservoir for hot water, it being provided with the inlet-pipe M for cold water, the latter leaving the boiler through the pipe N and passing downwardly into the pipe P, which leads to the water-holding chamber Q, located in the upper portion of the range above the gas-pipe R, which connects with the pipe B by means of the pipe S and is provided with valves and branches R, extending inwardly, whereby said chamber Q may be'heated.

Within the chamber Q is a partition T, whereby water is caused to flow in the direction of the arrows seen in Fig. 4, and thus leave the chamber Q'through the pipes U and U,'the pipe U leading to the boiler L and having the branch V, which leads to the pipe K, the pipe P being connected with-pipe J by the pipe J, whereupon'it will be seen that provision is made for a continuous circulation of water between the boiler and either chamber D or Q, or both chambers, the flow of the same being of course controlled by cocksor check-valves, as desired.

The chamber Q is provided with inwardlyextending legs V, having closed ends which are adapted to be filled with Water and terminate a short distance from each other, so that a passage W is provided, through which the heat may pass. a

It will be seen that the Water contained in the chambers D and Q is heated and circulates between the boiler L and said chambers, it being noticed that the water-chamber Q is at the upper portion of the range, and the water-chamber D constitutes the floor of a heating-chamber intermediate of the top and bottom of the range andv the open rim E, which supports said chamber D, the spaces of which rim form aseries of fines for the passage of the products of combustion from the burners of the branches or pipes 0 around the sides of said chamber and above the same to the upper chamber Q, and then through the openings of the top plate, as usual.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a gas-range,the combination of the top plate,water-heating chambers separated from each other and forming in conjunction with the sides of the range, a heating-chamber, the lower water-chamber being spaced from the sides of the range to form flues, a water-circuit having communication with said waterheating chambers and aburner situated below the lower Water-heating chamber.

2. In a gas-range, the combination of a top- Witnesses: v v
